Here's a breakdown:
* Coma: A temporary atmosphere that forms around the comet's nucleus as it approaches the Sun.
* Nucleus: The solid, icy core of the comet.
* Process: As the comet gets closer to the Sun, its icy nucleus warms up and starts to sublimate (turn directly from solid to gas). This gas and dust form the coma, giving the comet its characteristic hazy appearance.
The coma can be quite large, sometimes extending millions of kilometers. It's often described as a "fuzzy" or "hazy" cloud surrounding the nucleus.
